Balancing Abnormal Grid Decks with Temporary Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Abnormal-shaped grid decks, which require additional support frames to maintain balance during construction, occupy significant space and hinder workflow, making on-site construction inefficient.
Innovation Solution
Temporary beams are added to complete the rectangular profile of abnormal-shaped grid decks, allowing them to be balanced and secured on columns like normal decks, then removed post-fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional support frames are used to support abnormal-shaped grid decks, then the grid deck can be kept in balance, but the construction site space is occupied and workflow is hindered
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-positioning the centroid of the abnormal-shaped grid deck before installation. The construction guide marks the exact position where the grid deck's centroid should align with the column center, allowing the grid deck to be balanced and fixed without requiring additional support frames during the actual installation process.
2Adaptability or versatility
If abnormal-shaped grid decks are used to accommodate staircase layouts, then design flexibility is improved, but the grid deck cannot be sufficiently supported in balance
Solution Approach 1:
The patent applies local quality by focusing the balance adjustment mechanism at the centroid location of the abnormal-shaped grid deck. By ensuring the centroid aligns with the column center, the solution addresses the specific local requirement for balance without requiring changes to the overall abnormal shape or adding support structures throughout the entire grid deck.
3Productivity
If pre-casting method is adopted, then production rate and quality are improved, but on-site construction complexity increases for abnormal-shaped components
Solution Approach 1:
The patent applies the taking out principle by extracting the complex balance adjustment process from the actual installation process. The complexity is taken out and solved in advance through pre-calculated centroid positions and construction guide marks, leaving the on-site installation process simple and straightforward, requiring only alignment and fixation without additional support frames.

AI summary
In a method of laying out abnormally-shaped grid decks, the abnormally-shaped grid decks refer to grid decks having a cut-out at the corner thereof. It is usually a problem when laying out abnormally-shaped grid decks because they will be off-balance when they are laid on the columns. Support frames are used to support the abnormally-shaped grid decks and keep them balanced and stable on the columns. However, the support frames may obstruct the working route used in construction. The method adopted in the present invention adds temporary beams to maintain the abnormally-shaped grid decks by balancing them on the columns before they are fixed and secured thereon, and thereafter the temporary beams will be removed. This method can prevent using support frames which may obstruct the working route under construction.
